AI Thread Summary
The motion similar to popcorn popping is primarily described as simple projectile motion. When a kernel pops or a blender blade spins, it applies an impulse force that accelerates the object upwards. Once airborne, the object falls back down due to gravity, following the equation of motion governed by gravitational acceleration. The discussion emphasizes that this phenomenon can be analyzed using impulsive momentum equations. Overall, understanding this motion involves recognizing the transition from an impulse to gravitational influence.

I have been trying to understand motion similar to that of popcorn popping, or a blender popping things up when blending them. If someone could explain this motion it would be greatly appreciated.

It is simple projectile motion. The popping kernel, or spinning blade provides an impulse force which serves to accelerate the object. Once it is air borne it falls back under the influence of gravity.
 
Is there any specific equation which would represent this or is it just using simple impulsive momentum equations
 
After the impulse the the motion is governed by:

\ddot{x} = -g

once again it is projectile motion... do a web search.
 
Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario
I know that mass does not affect the acceleration in a simple pendulum undergoing SHM, but how does the mass on the spring that makes up the elastic pendulum affect its acceleration? Certainly, there must be a change due to the displacement from equilibrium caused by each differing mass? I am talking about finding the acceleration at a specific time on each trial with different masses and comparing them. How would they compare and why?
This has been discussed many times on PF, and will likely come up again, so the video might come handy.
